The figure used for this unit is from the Mage Knight Dungeons Heroic Quests: The Citadel set. Its model name is Captain Salidar.

MASTER OF GREAT CONSTRUCTS
After revealing an Order Marker on Talingul, instead of taking that turn with Talingul, you may take a turn with up to two large or huge Construct Heroes you control. A figure taking a turn with Master of Great Constructs must be within 8 clear sight spaces of Talingul before moving.

CHARACTER BIO:Constructs are mindless by nature, and easily controllable. Kurrok does as much to his Elemental minions, and now Utgar has summoned a sorcerer to harness the power of the great constructs. Elementals and Golems alike now serve the every whim of this great magician.

Care to elaborate? I would assume it is for the ability of Boreos picking up and moving Talingul for free early repositioning? Seems like a strong utility power especially for this synergy.

Yep.

You can move Talingul around and stop him from being engaged by melee.

Boreos also can be the first activation, and move Talingul to where he can see the construct you want to go second. This allows you to move Augamo or another construct to the other side of a glacier or a ruin without stranding him.
